2 chloroadenosine

2-Chloroadenosine 是腺苷类似物，可防止大鼠海马缺血细胞长期丢失。它是尿苷内流 (Ki:33 μM) 的竞争性抑制剂，高亲和力与硝基苄基硫肌苷结合 (Ki:0.18 mM)。它是一种人红细胞核苷转运体的转运渗透剂。

2-Chloroadenosine-5'-O-diphosphate是一种腺苷5'二磷酸（ADP）的衍生物。它在浓度依赖性的方式下，促进了人类富含血小板的血浆中的聚集，并抑制了由前列腺素E2（PGE2）诱导的环磷酸腺苷（cAMP）的产生。2-Chloroadenosine-5'-O-diphosphate引起预收缩的孤立的豚鼠taenia coli条带放松（pD2 = 6.74），降低大鼠的动脉血压。此外，它还抑制了热休克蛋白70（Hsp70）家族成员mortalin的ATP酶活性（人类酶的表观Ki = 45.05 µM）。

2-Chloroadenosine 5-triphosphate (2-chloro ATP), an analog of ATP and adenine nucleotide, functions as an antagonist of the purinergic P2Y1 receptor, inhibiting ADP-induced intracellular calcium mobilization in Jurkat cells with a Ki value of 2.3 µM. Additionally, 2-chloro ATP acts as an agonist of purinergic P2X receptors, demonstrated by inducing inward currents in HEK293 cells expressing either human bladder smooth muscle or rat PC12 receptor forms, with EC50 values of 0.5 and 2.5 µM, respectively. It also triggers relaxation in precontracted isolated guinea pig taenia caeci strips in a concentration-dependent fashion. Furthermore, 2-chloro ATP has been employed in research to investigate the substrate specificity of cyclic nucleotide-dependent protein kinases, including protein kinase A (PKA) and PKG.

Fluoro-nucleoside; Halo-nucleoside

2-Chloro-ADP (2-Chloroadenosine 5′-diphosphate) 是 Adenosine 5'-diphosphate（ADP）的衍生物，能够诱导血小板聚集并抑制腺苷酸环化酶 (adenylate cyclase) 的活性。该化合物抑制 Mortalin 的核苷酸结合域 (NBD)，其 Ki 值为 45.05 μM。
